Centuries ago, Terra, the world, was nearly destroyed by humans. In the wake of that destruction, Terra created the Guardians – a group sworn to protect Her. But humans have returned to their plundering ways and Terra needs the Guardians. The Guardians are now fractured, their leader murdered years before. They need a new leader – a new Terra Protectorum – but when a young girl is chosen outrage ensues. Questions demand answers.
 
Why has Terra selected a girl with no knowledge of the Guardians? Why has she chosen a human when it is the humans destroying the earth? And most importantly, why has she chosen the girl whose father murdered the last Terra Protectorum?
